To a/ZZ whom, it may concern:

Be it known that I, OswALD S. PULLIAM, a

citizen ofthe United States, residing at Pittsand a portion of the center sills of a car .em-

bodying. my invention; Fig. 2, a part elevational view and -part sectional viewof the two forms of transoms.

form of Fig. 1, showing the center casting in the form cfa center bearing; 'Fig 3, an elevational view of transom or body-bolster; Fig. 4, a part elevational and apart sectional view of a transom, showing center sills and center casting; and Fig. 5, a perspective vlflaw' of a center casting fitted into the center s1 s.

Referring to the drawings, I have shown The form shown by Figs. 1, 2, and 3 is designed for a body-bol ster andthe form of Fig. 4 for an intermediate transom'.` In both forms the transom 2', and-a vertical web 3,

comprises atop member 1, a bottom member bottom members. The bottom member 2 is cut away at its center, and the web is forme-d with two vertically-extending separated recesse's 4 4, each located a short distance from the center of the transom. Forming the recesses 4 4, as particularly shown by Fig. 3, leaves a'central web ortion 5, constituting an integral compression member. cesses 4 4 are adapted to receive draft members or center sills. In the drawings I have shown the center sills 6 in the form of channels, and while my invention is particularly designed for center sills of channel form it may be modified to ada t its use for center sills of othershapes. aidr'ecesses 4 4 are each located between theeentral web portion 5 and ribs or flanges 7,.wh:7.ch.latter extend outwardly from and at rightfangles to the vertical web ,3. A

`larly shown by Fig. 1. -ter casting S constitutes an important and joining said top and The re- 8 designa-tes a center casting comprising a bottom plate 9 and two disunited upright members 10. In the employment of this center casting in connection with the transom or body-.bolster shown by Figs. l1, 2, and 3 the bottom. plat-e of the casting is formed with .a center bearing member 11.' ,When applied to the intermediate transoms, the bearing member 1l is omitted.

The center sills are located in the recesses.

4 4 and extend through the same, as particu- The removable eencharacteristic feature of the present invention, providing a construction that may be readily applied to and removed from and be securely interlocked with the transom and center sills. It is adapted to be fitted into the recesses 4 4 and its upright members fitted into the center sills. As illustrated and as preferred, each upright member 10 is formed with slightljwinclined ledges l2 for the purposes of providing bearings for the top and bottom flanged portions 13 of the center sills. In addition to the arts mentioned I form two pockets 14 on tiie casting, which pockets are adapted to receive ribs or projections 15 of the transom.

The upright members are of such form that when they are assembled with the center sills rectangular projections are completed, which projections completely cesses of the transoms. What I c-laim is; y

' 1. In a car-body underframe, the combination with center sills in the form of channels, of a transom formed with separated refill 'the separated recesses to receive the een ter sills, a removable center casting comprising a bottom member and two disunited upright members, saidupright members located in the recesses ofthe transom, and means connecting the center sills, upright members and transom.

2..In a car-body underframe, the combi-v nation with two center sills in the form of channels, a transom provided with separated recesses-to receive the center sills, and a removable center casting having di'sunited up# right members adapted to be fitted into the center sills.

' 3. In a car-body underframe, the combination with two centerslls in the form of channels, a transom provided with separated tangular projections are formedwhich areI 'adapted to fill the recesses.

recesses to receive the center sills, and a .re-, movable center casting or filler colnprlslng a bottom member formed wlth a center bearing and 'twov disunite'd upright members adapted to be fitted into the transom."
